DOOR STOP AND CHECK.

SPECIFICATION formingpart of Letters Patent No. 594,327, dated November23, 1897.

Application filed. February 16, 1897. Serial No. 623,596. (No model.)

To all whom it may concern.-

Be it known that I, JACOB H. COFFMAN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a cer tain new and useful Improvement inDoor Stops and Checks, of which the following is a specification.

My invention relates to a new and useful improvement in door andwindow-shutter checks and fasteners, and has for its object to provide asimple, cheap, and effective device which may be readily applied to thewashboard of a room and serve to prevent the door or knobs carriedthereby from'coming in contact with the wall and also retain the door inits open position, but permit its being closed when sufficient strain isbrought to bear thereon. My'improvement is likewise adapted for use inconnection with window-shutters, and serves the same general purpose aswhen applied to a door.

With these ends in view this invention consists in the details ofconstruction-and combination of elements hereinafter set forth, and thenspecifically designated by the claim.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, its constructionand operation will now be described in detail, referring to theaccompanying drawings, forming a part of this specification, in which'Figure 1 is a top View of a door and section of a wall and door-casing,showing my improvement applied thereto; Fig. 2, an enlarged view of myimprovement, showing the striker in engagement with the arms of thecheck; Fig. 3, a front elevation of the check,

Fig. 4:, an enlarged side elevation of the striker, the escutcheon-platebeing in section,

and, if desired, a third screw may be passed through the upper eye, alsoformed by this opening; but in practice I have found that two screws aresufficient for all practical purposes. The arms are of such length as togive the proper amount of resiliency, so that they maybe sprung openwhen occasion requires, as hereinafter set forth. The arms at theirouter ends are turned slightly inward, bringing their ends in contactwith each other, which ends are squared, thus producing a V- shapednotch, as indicated at D. The striker E is also formed of a single pieceof wire having the eyes F formed thereon, through which the screws G maybe passed for the securement of said striker to the door. The screwswhich pass through these eyes are also passed through theescutcheon-plate H, interposed between the striker and the surface ofthe door, as clearly shown, so that when the door is swung open thestriker will enter the V'- shaped notch at the ends of the arms, therebyspringing said arms open and permitting the striker to pass between thesame, which will then close by their spring action and retain thestriker and the door in its open position. When the striker passesbetween the outer ends of the arms, the escutcheon-plate will come incontact with said outer ends, thereby preventing the marring of thesurface of the door and also arresting the door in its outward movement,and as the arms are of spring material the door will be brought to restwithout undue concussion.

When a door is held open by my improvement and it is desired to closethe same, it is only necessary to exert sufficient strain thereon in areverse direction to overcome the action of the spring-arms upon thestriker, when the latter will be drawn from between said arms, thuspermitting the door to be closed in the usual manner.

From this description it will be seen that a very cheap and efiectivecheck is provided for a door, which not only serves the purpose ofpreventing undue concussion to the door when finally swung open, butwhich will also retain the door in its opened position against ordinarydrafts or pressures.

Having thus fully described my invention, what I claim as new and usefulis- In combination, a door-stop consisting of a single piece of Wirebent to produce two parallel arms of equal length, the ends of the wirebeing squared, the loop portion being then bent at right angles to thearms and arranged to form eyes for the passage of screws, the arms beingbent toward each other, the edges of the ends meeting at one point andforming a V-shaped notch, and a striker or retainer formed of a singlepiece of wire having its ends bent to produce eyes, and the body portionraised or set away from the door or shutter, screws adapted to passthrough said eyes, and an escutcheon-plate secured between the retainerand the door by the screws, as and for the purpose described.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.

JAGOB H. COFFMAN.
